연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A large mobile crane including an undercarriage. The undercarriage includes a middle section between tracks, wherein a distance between the tracks can be increased or decreased by the insertion or removal of expansion parts. The two tracks are connected on opposite sides of the undercarriage to permit movement of the large mobile crane. The undercarriage also includes a drive unit, a superstructure, one or more control stations, at least two main booms, at least one derrick boom, and at least two lifting devices and counterweights. The counterweights are either arranged separately of or mounted on the undercarriage. The large mobile crane further includes a circular track, and support rollers attached to the superstructure, wherein the support rollers ride on the circular track, and wherein the circular track is an integral part of the expansion parts.

1. Large mobile crane comprising an undercarriage, wherein the undercarriage comprises a middle section between tracks, wherein a distance between the tracks can be increased or decreased by the insertion or removal of expansion parts, said two tracks connected on opposite sides of the undercarriage to permit movement of the large mobile crane, a drive unit, a superstructure, one or more control stations, at least two main booms, at least one derrick boom, and at least two lifting devices and counterweights, wherein said counterweights are either arranged separately of or mounted on the undercarriage, and wherein the large mobile crane further comprises a circular track, and support rollers attached to the superstructure, wherein the support rollers ride on the circular track, and wherein the circular track is an integral part of the expansion parts. 2. Large mobile crane according to claim 1, wherein the at least two main booms are mounted symmetrically with respect to each other on the superstructure, the booms being connected to each other by connecting elements so that they are rigid with respect to moments. 3. Large mobile crane according to claim 1, wherein the counterweights are arranged both separately and on the undercarriage. 4. Large mobile crane according to claim 1, wherein the main booms are paired with derrick booms, which are connected to each other by connecting elements. 5. Large mobile crane according to claim 1, wherein the undercarriage is a crawler undercarriage and the two tracks are crawler tracks. 6. Large mobile crane according to claim 5, wherein the crawler undercarriage comprises a pair of crawler carriers, which can be lengthened or shortened in modular fashion by the insertion or removal of intermediate pieces. 7. Large mobile crane according to claim 6, wherein the crawler carriers are lengthened or shortened along a driving direction, which is defined by the crawler carriers. 8. Large mobile crane according to claim 1, wherein the at least two main booms are arranged next to each other on the superstructure and are connected to each other so that they are rigid with respect to moments, and wherein the main booms are paired with at least two derrick booms. 9. Large mobile crane according to claim 1, wherein the undercarriage has crawler-type tracks arranged one behind the other or with an offset. 10. Large mobile crane according to claim 1, further comprising a pair of bottom hook blocks which are combined with each other by means of a connecting crosspiece. 11. A kit comprising: the large mobile crane according to claim 1,wherein the undercarriage further comprises crawler carriers, each surrounded by a respective one of the tracks,intermediate pieces configured to be selectively inserted in a crawler carrier of each track,wherein each of the crawler carriers is divided into a front crawler carrier part and a rear crawler carrier part configured to result in a first footprint and to support the respective one of the tracks and arranged in a longitudinal direction of the crawler carriers,wherein at least one of the intermediate pieces, when in use, is inserted between the front crawler carrier part and the rear crawler carrier part of each of the crawler carriers, thereby elongating the crawler carriers which are each surrounded by an elongated crawler track, andwherein said elongated crawler carriers provide a second footprint of the large mobile crane, the second footprint being larger than the first footprint. 12. Large mobile crane according to claim 11, wherein at least one of said expansion parts is arranged between the middle section and one of the tracks. 13. Large mobile crane according to claim 11, wherein the distance between the tracks to be increased or decreased by the insertion or removal of the expansion parts is oriented perpendicularly to a driving direction of the crane, wherein the driving direction is defined by the tracks. 14. Large mobile crane according to claim 11, wherein the crawler carriers are lengthened or shortened along a driving direction, which is defined by the crawler carriers. 15. Large mobile crane according claim 1, wherein the whole circular track is completely arranged on the expansion parts. 16. Large mobile crane according claim 1, wherein the circular track surrounds the middle section, such that the circular track is spaced apart from the middle section. 17. Large mobile crane according to claim 1, wherein at least one of said expansion parts is arranged between the middle section and one of the tracks. 18. Large mobile crane according to claim 1, wherein the distance between the tracks to be increased or decreased by the insertion or removal of the expansion parts is oriented perpendicularly to a driving direction of the crane, wherein the driving direction is defined by the tracks. 19. A large mobile crane according to claim 1, wherein the undercarriage further comprises crawler carriers, each surrounded by a respective one of the tracks,intermediate pieces configured to be selectively inserted in a crawler carrier of each track,wherein each of the crawler carriers is formed by a front crawler carrier part and a rear crawler carrier part configured to result in a first footprint and to support the respective one of the tracks and arranged in a longitudinal direction of the crawler carriers,wherein elongated crawler carriers are formed by inserting at least one of the intermediate pieces between the front crawler carrier part and the rear crawler carrier part of each of the crawler carriers thereby the elongated crawler carriers each being surrounded by an elongated crawler track, andwherein said elongated crawler carriers provide a second footprint of the large mobile crane, the second footprint being larger than the first footprint.
